LUBRICATOR.

l SPECIFICATION forming part of Letters Patent N o. 502,139, dated July 25,1893.

Application iiled March 30, 1893. Serial No. 468,291. (No model.)

To all whom. it may concern.-

Be it known that I, ROBERT PLACE, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented a new and Improved Attachment for Oiling Cross-Heads of Steam- Engines, Pumps, &c., of which the following is a specification.

This is a device or attachment for keeping 'the cross-heads and crank-pins of steam engines, pumps, dac., automatically oiled, and

the nature of the invention is fully described below and illustrated in the accompanying drawings, in which- Figure 1 is an elevation showing a portion of a steam-engine with my attachment applied, the cross-head being shown on the dead center in lfull lines, and at the ends of the stroke in broken lines. Fig. 2 is a vert-ical section taken on line Fig. l, showing such parts as are necessary to illustrate the invention. Fig. 3 is a detail in elevation and vertical section of a swivel or swing joint below described. Fig. 4 shows elevations of the telescopic tubes detached and'separated. Fig. 5 is a detached view of the hollowv spindle, described below.

Similar letters of reference indicate corresponding parts.

A represents a portion of a steam engine of any suitable type.

A is the bed, B the cross head, a the piston rod and a the connecting rod.

A stand O is bolted to the bed A of the engine at the exact center of the stroke of the cross-head. A casting C is bolted to this stand and has screwed in its top an automatic lubricator D. A hollowspindle E is screwed into the outer end of the casting C coincidently with the end of the oil-passage D connecting with the lubricator D, and the outer end of this hollow spindle is provided with a flange E,-Figs. 2, 3, and 5. This flange lies in a .small circular chamber F in the swingjoint or swivel-joint F of right angled or elbow shape, as shown, and provided with an oil passage Ff which connects with the end of the passage in the hollow spindle. A stuffing box or cap, having a smooth bore, lies on the hollow spindle E, and is externally screw-threaded at b', whereby it is screwed into thev joint F until its annular iiange d bears against said joint. The rear end of the stuffing box is externally screw-threaded to receive the gland e. Thus the joint F easily swings on the tubular spindle E. The opposite end of this joint is internally screwthreaded to receive a piece of tubing or pipe H, whose end H is externally screw-threaded for the purpose. (Figs. 2, 3, and 4.) This tube H works telescopically within a large tube I to the upper end-I of which is screwed a gland or stuffing box f. The opposite end of the tube I is screwed into another swingjoint J, similar in construction to the joint F, and provided at its opposite end with a stuffing box g, g', h, similar to that above described and lettered Z) cl e. A tube K provided with a flange K makes a swivel connection with the joint H in the same manner as the tube E with the joint F, and the other end of the said tube K is screwed into the cross-head B, as shown, coincidently with the oil-passage B therein.

The operation is as follows: When the cross-head is on the center, as shown in Fig. l, the smaller telescopic tube H is for nearly its entirely length within the larger tube I, but as the cross-head moves away from the center, the tube H draws out of the tube I, and, on its return toward the center, moves in again. In other words, the tubes move telescopically in order to accompany the crosshead as it makes its strokes. The swing-joints F and J turn, as will readily be understood, upon the tubular spindles E and K with the movements of the cross-head. During these operations the oil has free passage from the automatic lubricator D through the passage IOO Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination of the bracket or casting 5 X supported by the engine bed and provided with the passage D, a iubricator mounted thereon, the tubular spindle E extending from said casting and connecting with said passage and provided with the flange E', the swingjoint F provided with the passage F, anged stufng box b (l, similar tubular spindle K eX- tending from the er0ss-head `and connecting with a passage B therein, similar swing-joint hung on the end of said spindle, and the telescopically arranged tubes H I extending respectively from the swing-joints F J and projecting one into the other, substantially as described.
